DARPA Falcon HTV-2
DARPA - Falcon Hypersonic Technology Vehicle 2 (Falcon HTV-2) is an unmanned, rocket-launched, maneuverable aircraft that glides through the Earth’s atmosphere at incredibly fast speeds—Mach 20 (approximately 13,000 miles per hour). At HTV-2 speeds, flight time between New York City and Los Angeles would be less than 12 minutes. The HTV-2 vehicle is a “data truck” with numerous sensors that collect data in an uncertain operating envelope. more> http://tinyurl.com/cllvddk
